Rank #34
Kult: Divinity Lost
Kult: Divinity Lost uses investigation to peel away ordinary reality, with missing people, cults, trauma, and occult clues revealing the machinery behind the world.
Rank #37
Delta Green
Delta Green fits investigation because the casework is the trap: agents follow leads, interview witnesses, and assemble evidence while the truth damages their lives and sanity.
Rank #39
Vaesen
Vaesen makes investigation folkloric and social: characters read omens, question locals, uncover old wrongs, and learn why the supernatural problem cannot simply be fought.
Rank #72
Call of Cthulhu
Call of Cthulhu remains a classic investigation game because documents, interviews, crime scenes, and occult traces slowly point toward truths the characters are rarely equipped to survive.
Rank #1014

Arkham Horror
Arkham Horror fits investigation when you want pulp occult casework: strange locations, scattered clues, dangerous artifacts, and a mystery that points toward something larger than one scene.
Directory entry
Ashen Stars
Ashen Stars is investigation-forward space opera, using GUMSHOE to keep leads moving while starship contracts reveal crimes, politics, alien cultures, and weird science.
Directory entry
Blade Runner
Blade Runner works best when the investigation is moral as much as procedural, asking characters to weigh evidence, empathy, institutional pressure, and what it means to be human.
Directory entry
Brindlewood Bay
Brindlewood Bay is one of the clearest investigation picks because clues are guaranteed to matter, but the final answer emerges from a theory built at the table instead of a prewritten solution.
Directory entry

Candela Obscura fits investigation when the case structure, occult evidence, and character scars all matter, turning each assignment into both a mystery and a personal risk.
Directory entry
City of Mist
City of Mist fits investigation when clue-gathering is tied to identity, symbolism, and noir pressure, with each case pulling characters deeper into the myths behind the city.
Directory entry
Cthulhu Dark
Cthulhu Dark keeps investigation stark and focused: characters can find the truth, but each revelation increases the sense that understanding will not make them safe.
Directory entry
Cthulhu Hack
The Cthulhu Hack fits investigation when you want fast, pressure-heavy clue chasing, with dwindling resources and consequences pushing the case toward horror instead of procedure.
Directory entry
Dead of Night
Dead of Night belongs here when the fun is figuring out the shape of a horror-movie threat quickly enough to survive the night, not building a long procedural campaign.
Directory entry
iHunt
iHunt works for investigation because the job usually starts with tracking a threat, understanding who is being exploited, and finding leverage before anyone can solve it with violence.
Directory entry
Liminal Horror
Liminal Horror is a strong fit for modern weird investigations where ordinary places become threatening, clues are sparse, and understanding the anomaly rarely means controlling it.
Directory entry
Mage: The Awakening
Mage: The Awakening turns investigation into occult problem-solving, where mysteries, hidden causes, and symbolic patterns matter as much as any spell or confrontation.
Directory entry
Technoir
Technoir shines at conspiracy investigation because contacts, favors, tags, and liabilities create a plot web that grows from player choices instead of a fixed trail of clues.
Directory entry
The Dresden Files RPG
The Dresden Files RPG fits investigation through urban fantasy casework: suspects, favors, supernatural politics, and hidden motives matter before the wizardry starts flying.
Directory entry
TimeWatch RPG
TimeWatch belongs here because the central question is often what changed in history, who changed it, and how to repair the timeline without making the damage worse.
Directory entry
Trail of Cthulhu
Trail of Cthulhu is built for investigation-first horror: GUMSHOE keeps essential clues moving while the real tension comes from what those clues uncover.
Directory entry
Triangle Agency
Triangle Agency makes investigation bureaucratic and surreal, sending agents to classify anomalies, follow impossible evidence, and decide how much of the official story to trust.
